2.4: Writing Equations of Lines

Goals

• Writing Linear Equations

– Converse of given a line find:

• Intercepts

• Slope

• Points on the line

• Writing Direct Equations

– Understanding rates of change that are related to

each other

Slope-Intercept Form

Given the slope m and y-intercept b, use the

equation: y=mx+b

E.g.,1: My y-intercept is 50 and the slope is 2.

E.g., 2: Slope is 3/2, has points (-2, -4) and (2, 2).

E.g., 3: Perpendicular and parallel to y=2x-3

7

Perry High School

Point-Slope Form

Given:

(a)Slope m and a point (x1,y1), OR

(b)Two points (x1,y1), (x2,y2)

E.g., 4: m=2 and point (2,3)

E.g., 5: points (2,1), (-1,-2)

Direct Variation

Note 1: Constant k can be a fraction

Note 2: The y-intercept is zero

2.5: Correlation and Best-Fitting Lines

a.k.a. some very useful applications

Goals

• Scatter Plots and Correlation

– Plotting Data on Graph, Seeing if the data is

related.

• Approximating Best-Fitting Lines

– Give an equation that roughly fits the data.

Correlation

20

Perry High School

Kevin M. Bond, PHD

Approximate a Line of Best Fit Method One:

1. Draw Scatter Plot

2. Sketch a line that “most

follows the pattern”.

3. Choose two points on

this line.

4. Find an equation using

those two points.

Method Two:


2. Pick two points that

“most represent the

data”.


those two points.

Note: This is not THE line of best fit, but a guess of that line.

2.6: Linear Inequalities in Two Variables

Goals

• Graphing Linear Inequalities

– Scaling inequalities up to 2-dimensions

• Using Linear Inequalities in Real Life

– Applications and such

Graphing

An inequality in two variables graphs ½ of a plane:

1. Graph the boundary line. Use solid line only if

equation has “equal to” aspect, else dash the

line.

2. Test points above and/or below the line. Shade

if test point is a solution.

E.g.,1: y>2

E.g., 2: y=2x
